Until Euro-American colonization, Indigenous people used fire to modify eco-cultural systems, developing robust Traditional Ecological Knowledge (TEK). Since 1980, wildfire activity has increased due to fire suppression and climate change. In 2017, i

Spatiotemporal Variability of Arctic Soil Moisture Detected from High-Resolution RADARSAT-2 SAR Data
Publikováno v:
Advances in Meteorology, Vol 2018 (2018)
Various methods are used to determine soil moisture information from synthetic aperture radar (SAR) data, but none specific to High Arctic regions and their unique physical characteristics. This research presents a method for determining, at high spa

Vegetation in the Arctic is often sparse, spatially heterogeneous, and difficult to model. Synthetic Aperture Radar (SAR) has shown some promise in above-ground phytomass estimation at sub-arctic latitudes, but the utility of this type of data is not

Satellite-derived spectral indices such as the relativized burn ratio (RBR) allow fire severity maps to be produced in a relatively straightforward manner across multiple fires and broad spatial extents. These indices often have strong relationships

Active layer detachments (ALDs) are a common form of permafrost slope disturbance that pose a serious risk for infrastructure and can impact environmental and ecological stability in Arctic regions. Effective recognition and detection of slope distur

Research was initiated in July 2004 to determine if change-detection methods employing synthetic aperture radar (SAR) could be applied to estimate change in soil moisture over a growing season for a site in the Canadian High Arctic. Two change-detect

The grizzly bear (Ursus arctos L.) is a species that is widely recognized as an indicator of ecosystem health in west-central Alberta. Agricultural activities, oil and gas exploration and extraction, forestry, and recreation can all contribute to gri
